Sand mastic for homes and businesses in Halland
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on tenement windows, timber door frames and brick reveals, and people most often call us about gaps between timber frames and stone or brick and modern sealant on a period surround.
Homes in small places like Halland often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Leave it or put it right?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Halland can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

When to call us in Halland
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Weathered mastic on the most exposed windows
If you let a flat or house near Uckfield station, older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
What sealant work can’t fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Masonry that needs repairing
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
